Sub HideallFields
<STYLE type=text/css>body { margin: 0 0 0 0; padding:0 0 0 0 }td,div { font-family:Trebuchet MS;font-size:8pt;vertical-align:top }body { margin: 0 0 0 0; padding:0 0 0 0 }.transcript { background-color:#d2d2d2; }.messageBlock { margin-left:4px; margin-bottom:3px }.message { margin-left:100px; word-wrap:break-word; white-space:-moz-pre-wrap; _white-space
